The basic thought of the present invention is to consider relationship between API complexities, API frequency of use and API, API Quantity come to test case carry out priority ranking.
Below with reference to Fig. 1 describe it is according to an embodiment of the invention for multiple test cases of the APP based on API into The flow of the method for row major grade sequence.
Fig. 1 shows the flow chart of prioritization method according to an embodiment of the invention.As shown in Figure 1, this is preferential Grade sort method includes the following steps:For each test case in the multiple test case, the API that the test case calls is determined Gather (step S1);According to the frequency of use of each API in the complexity score of each API in API set, API set At least one of score, the coupling score of the test case, API quantity scores of the test case, calculate the evaluation of the test case Score, wherein the coupling score of the test case reflects the coupling tightness degree (step between the API of test case calling S2);And the evaluation score according to the multiple test case, priority ranking (step S3) is carried out to the multiple test case.
In step sl, for each test case in the multiple test case, the API set that the test case calls is determined It closes.
Specifically, the test case can be run, the API set that all API called with the determining test case are constituted. The source code of the test case and the source code of APP can be analyzed, the code snippet that the tested example to position App is triggered, and The API Calls to Mobile Development frame covered in the code snippet are obtained, to determine API set.
In step s 2, made according to each API in the complexity score of each API in API set, API set With at least one of frequency score, the coupling score of the test case, the API quantity scores of the test case, the test case is calculated Evaluation score.
Complicated API is relative to simple API, it is easier to introduce loophole (bug).Therefore, it considers involved by test case The complexity score of API, to calculate the evaluation score of test case.
Specifically, the complexity score of API embodies the API in all API, needed for number of parameters and/or calling Amount of source code in terms of distribution, according to the number of parameters of API and/or call API needed for amount of source code calculate.Wherein, It includes calling the line number of the source code needed for API to call the amount of source code needed for API.
Assuming that the number for the parameter that API has is np, to call the API to need the line number of source code write be nl.
The complexity score A C of API can be calculated by following formula (1).
AC=wnormalized (np)+(1-w) normalized (nl) (1)
Wherein, normalized () indicates normalized function, and w is weighting coefficient.
According to the different distributions of np and nl, different normalized functions may be used.For example, if np or nl obeys mark Quasi normal distribution then may be used Z-score (Z score model) to be normalized, normalized function represented following In the formula (2) of normalized (), μ is the mean value of all samples, and σ is the standard deviation of all samples, x*For dependent variable, x is Independent variable.
x*=(x- μ)/σ (2)
If np or nl obediences are uniformly distributed, minimum value-maximum value normalized function may be used, return in following representatives One changes in the formula (3) of function normalized (), and min represents the minimum value of all samples, and max represents all samples most Big value, x*For dependent variable, x is independent variable.
x*=(x-min)/(max-min) (3)
It stores the number of parameters of each API in API statistical information datas library, called needed for each API in all App Source code line number and the numbers that are called in the source code of all APP of each API.Each calling of API API The line number nl for the source code write is needed to be equal to the average value for the line number for calling the source code needed for the API in all App.
Whenever APP change or update when, APP call API number of parameters, call API needed for amount of source code, API The number being called in the source code of APP is also updated.
The frequency of use score of API exists according to the API numbers and all API being called in the source code of all APP The sum being called in the source code of all APP calculates.The API that the API ratios being commonly used are not frequently used is easier to meet with bug。
As described above, being stored with what each API was called in the source code of all APP in API statistical information datas library Number.When being changed APP or is updated, which can also update.
The frequency of use score A F of API can for example be calculated by following formula (4).
AF=(invoke_times (API))/(invoke_times (all APIs)) (4)
Wherein, invoke_times () indicates the call number retrieved from API statistical information datas library, API table The API of its frequency of use score will be calculated by showing, allAPIs indicates all API.
It should be noted that the complexity score of API and the frequency of use score of API and are described below both for the score of API Test case coupling score and test case quantity score both for test case score.Due to the complexity score of API It is that the API being directed in the API set that test case calls is calculated with frequency of use score, so complexity score and frequency of use Score finally also embodies the information of test case.
The coupling score of test case reflects the coupling tightness degree between the API of test case calling.The coupling of test case Closing score can calculate according to the sum of the input/output relation between the API in API set, the API in API set.
If in the source code for the App that the test case is called, there are direct input/output relations by two API, then There is coupled relations by the two API.Fig. 2 shows illustrative API couplings to scheme.In fig. 2, each node is an API It calls, if two API, there is coupled relation, there are sides between the two nodes.For following API Calls set, Fig. 2 shows the coupled relation between API.
A=API_invoke1 ();
B=API_invoke2 (a);
C=API_invoke3 ();
D=API_invoke4 (b);
Wherein, a, b, c, d indicate the input and output of API Calls.API_invoke1、API_invoke2、API_ Invoke3, API_invoke4 indicate API Calls.
The coupling score A CD of test case can be calculated by following formula (5).
In formula (5), molecule number_of_edges is the number on side in coupling figure, and N is that test case is called The sum of API.For example, it is assumed that N is equal to 4, and the number on the side in Fig. 2 is 2, then the ACD being calculated according to formula (5) is equal to 1/3。
ACD=(number_of_edges)/(N (N-1)/2) (5)
The sum for the API that the API quantity score of test case is called according to total, all test case of the API in API set It calculates.
Specifically, the API quantity scores of test case are equal to the sum and all test cases calling of the API in API set The quotient of the sum of API.
The evaluation score A PI_coverage_score of test case is equal to the complexity score of each API in API set ACi, each API in API set frequency of use score A Fi, the coupling score A CD of the test case, the test case API numbers The weighted sum of point n/N is measured, such as shown in following formula (6).
Wherein, N is the sum for the API that all test cases call, and n is the sum of the API in API set, w1、w2、w3It is to add Weight coefficient.
In step s3, according to the evaluation score of the multiple test case, priority row is carried out to the multiple test case Sequence.
The evaluation score of test case is higher, and ranking is more forward.Test case in the top can be tested preferentially.Also it can incite somebody to action The test case of the most preceding predetermined number of ranking is selected, and abandons other test cases.
